Thick Film Substrates & Packages (Plating)


Thick Film (Plating)
Thick film metallized substrates have been developed by combining proven ceramic materials and thick film metallization technology. Various patterning technologies allow us to support custom-made requirements. Main applications are semiconductor lasers, medical lasers and other similar products.
